Ron:I have done additional reserch on the internet and discovered that Ford had sealed the bearing hub to the steering knuckle with RTV on certain years. I opened my other front wheel and can clearly see black RTV oozing from the gap. Various users suggested applying a sovent (brake cleaner) to loosen the RTV. I have tried it but with no success. I will let it soak overnight.
If you have any suggestions for lossening the RTV, I am all ears. I have tried wedging three screwdrivers in at each bolt hole to try and get some separation so that I can get a pry bar in there but still no success. There is a very small gap now between the bearing hub and the knuckle but it is still stuck tight.
